Great for A cup chest!

This top is very comfortable, it provides enough coverage while flattering my body, and I really appreciate the padding - the built-in bra is what drew me to this top. The color is beautiful!
I appreciate the company’s effort to be very transparent about the fabric composition. Not everything here is plant-based, but I had an opportunity to review the composition before making my purchase. I would consider buying more tops from them.

Loved the color

I looooove the blue
I’m a 34B and I ordered the small. It fits a little tight and I think next time I’ll got for the M.
The fabric is soft
We’ll see how it does after a few washes

Supportive and comfy

Love this bra! Supportive but I'm not afraid of accidentally choking myself when I take it off. And the material is so soft and nice. Color is pretty too. Size chart said I should get a medium and the medium fit great!

Supportive, cute, everything stays in place

Love this fit of this sports bra. It’s comfortable and there’s no cutting into the armpits. The color is super cute and vibrant for a blue.

I’m excited to work out in this bra. I ordered a S. I’m a 34B, and this thing is snug, which is perfect for working out.

They fit me perfectly and I feel secure. I bought a size small and I especially like to wear them in hot yoga or hot Pilates classes or I don’t wear a shirt over. I don’t feel like I’m going to fall out of them. I wish you’d make even more colors. but absolutely they’re great thank you.

I love the fit! So glad to have found non-toxic activewear that looks as good or better than my conventional

I'm very happy with these bras! The texture is smooth and comfy, and I love knowing I can wear them all day because of Aktiiv's extra skin-safe fabrics. I'm a 32C/D and got a size small - the bra kinda pushes my boobs up and together (I usually enjoy more flattening compression) but it is not enough that it bothers me. Also, I made a mistake in my order at first, but Aktiiv's customer service team was quick, helpful, and very friendly with providing solutions!

Love the color, the material is super soft. Feels like a nice medium support bra that fits my 32-C I got the small.

This is a great bra. Excellent quality and super soft. I have one request for
äktiiv: please make a sports bra just like this but with sewn-in pads! I would absolutely love it (and buy it)!

LOVE the fabric. True performance fabric. Supportive. Runs Small. 30D purchase small based on size chart recommendations, I had to exchanged for a medium. Design is nothing special but it's a solid basic and does the job. Looking forward to some more dynamic and attractive sports bra designs in the future!

I could have used a XL likely for 38C-D chest. This works for sure and will be used as my primary for more intense workouts, but the band does ride up a bit. I will say, this fabric is definitely the closest to non-sustainable I’ve experienced. So glad it’s healthy for me and performs!

I think this bra has a really nice material and is decently supportive. I'm a 32DDD and purchased a Medium. It fits well but definitely is not supportive enough for HIIT or more intense cardio. Works well for lower impact activities like pilates, yoga, strength training, etc. Would love to see a bra that's for higher impact/larger chests!

This is my new FAVORITE sports bra! I have been on the search for a clean brand sports bra and I could wear this all day and night. So buttery soft and ultra supportive- I like HIIT exercises, riding dirt bikes and am a volleyball coach and this sports bra support is 100% with all those activities. I run between a medium/large so I ordered a large and its the perfect fit, not too big. Do yourself a favor and try it!

Although I waited a while to receive it (they’re so popular!) I LOVE this sports bra. The elasticity, compressive quality and overall fit are perfect! 13/10 recommend!

I’ve been looking for a eco friendly sports bra that offers good support, looks great and feels great. I finally found one! I’ve put this bra to work in spin class where I am sweating and moving a lot. I’ve ordered these in all the colors available now.
